Headers, CBE, HFCS

Trips · 01-24-2014, 11:20 AM

While I agree with members suggestions that gains are very minimal for the expense of header/labor $$$

I might suggest NST lightweight under drive pulleys as an alternative.

The gains will be in line with a short header swap and less expensive altogether.

Hey, it's your money but consider this. How will changing a factory tuned header to an aftermarket header produce any noticeable gains from an already highly tuned engine? You can only squeeze so much power out from this engine. These engines being highly tuned already don't respond the same as for example, a small block chevy would with similar mods. Money better spent on a good tune vice headers. If you want real power gains, go FI.

How about trying a different approach OP. It's not ALL about producing higher HP. Have you considered modifications to save weight? Z1 has a 2 piece rotor set available at a decent price point. NST underdrive pulley is another good option. How about a lightweight battery?

You see where I'm going with this.

No reason to do headers if you don't install them your selves or you have to run HFC's. Your just robbing yourself. Cost of header install and the restrictions of HFC's.

If long tubes are illegal, I'm sure a header swap with HFCs is too... Actually, I know it's illegal...

Stillen and Berk make HFCs for the 350Z too... The ONLY difference is the flange.

Exactly. If you're going to WASTE your $600+ on Stillen headers I dont understand why you don't save an extra few hundred to get better than stock headers...

The best review I've seen on a friend's car was 7hp... Another friend, +2HP... The dyno reads +/- 5hp anyways...

At this point we've all told the OP it's a waste of time and money for no power. If he wants to go find out himself, go for it.

Ok. Beer time.

I am new or the 370z and was dead set on buying headers. After listening to so,e feedback I think It doesn't make sense plus the oem heat shield has to be removed with some do these headers thus creating more heat issues. I just thought it didn't seem worth it.

Guys, (or the ones who have been here a while)

Let's just back away...

Sorry not everyone is 50 years old and knows everything about cars and their upgrades. So go ahead and " let's just back away..." Since you were no help at all to me, Chuck and nismo270 were the only ones that had an impact on my decisions.

I'm not 50 either, I just turned 24. I'm telling people to back away to not bash you. I provided help. Not my fault you cannot see it.
